Masson Fontana kit is used in a specific method for proving argentaffin granules in histological sections, based on the reduction of silver nitrate to elemental silver. Melanin is a pigment usually found in skin, hair, retina, and some parts of the central nervous system. In order to avoid getting false-positive results, BioGnost’s Masson Fontana kit contains reagents for melanin depigmentation. Depigmentation is conducted on a control section before silver impregnation.
Masson Fontana kit
Six-reagent melanin and argentaffin granule staining kit, based on the reduction of silver nitrate to elemental silver. Melanin is a brown-black pigment normally present in the hair, skin, retina, iris and certain parts of CNS. Argentaffin granules are found in carcinoid tumours.
